Competing Orders and Ultrafast Energy Transfer at the Quantum Limit in a NbSn Superconductor Probed by Terahertz Electrodynamics
X. Yang, X. Zhao, C. Vaswani +10
We report the low-energy electrodynamics of a moderately clean A15 superconductor (SC) following ultrafast excitation to understand and manipulate terahertz (THz) quasi--particle (…
Simulation of alnico coercivity
Liqin Ke, Ralph Skomski, Todd D. Hoffmann +6
Micromagnetic simulations of alnico show substantial deviations from Stoner-Wohlfarth behavior due to the unique size and spatial distribution of the rod-like Fe-Co phase formed du…
Electronic and optical properties of novel carbon allotropes
Zhanyu Wang, R. J. Zhang, Y. X. Zheng +7
The phonon properties, electronic structures and optical properties of novel carbon allotropes, such as monolayer penta-graphene (PG), double-layer PG and T12-carbon, were explored…
Adaptive Genetic Algorithm for Crystal Structure Prediction
S. Q. Wu, M. Ji, C. Z. Wang +5
We present a genetic algorithm (GA) for structural search that combines the speed of structure exploration by classical potentials with the accuracy of density functional theory (D…
Electronic and spin transport properties of zigzag graphene nanoribbon mediated by metal adatom: A study by QUAMBO-NEGF approach
G. P. Zhang, Xiaojie Liu, C. Z. Wang +3
Structural and electronic properties, including deformation, magnetic moment, Mulliken population, bond order as well as electronic transport properties, of zigzag graphene nanorib…
Including many-body screening into self-consistent calculations: Tight-binding model studies with the Gutzwiller approximation
Y. X. Yao, C. Z. Wang, K. M. Ho
We introduce a scheme to include many-body screening processes explicitly into a set of self-consistent equations for electronic structure calculations using the Gutzwiller approxi…
Structures and energetics of hydrocarbon molecules in a wide hydrogen chemical potential range
Y. X. Yao, C. Rareshide, T. L. Chan +2
We report a collection of lowest-energy structures of hydrocarbon molecules C_{m}H_{n} (m=1-18; n=0-2m+2). The structures are examined within a wide hydrogen chemical potential ran…
Dynamic Local Distortions in Ferroelectrics
H. Krakauer, R. Yu, C. -Z. Wang +2
Molecular-dynamics simulations of KNbO reveal preformed dynamic chain-like structures, present even in the paraelectric phase, that are related to the softening of phonon branc…
